This may not be a direct answer to your question but you can natively install OpenOffice.org which has office 2007 support so you can open, and save files as office 2007 documents. It will work much better under linux because it is a native app and you shouldnt have any compatibility problems.

The one thing lacking from this solution is Microsoft Outlook which can be replaced with Evolution email client if you need exchange support, or Thunderbird for pop3/imap email.

If I were in a position where I _needed_ to run Office2k7, I would definitely opt for VirtualBox and seamless mode. Seamless mode allows you to run a windows desktop environment on top of your linux desktop, and launch windows programs in a very hand way.

You won't have the hassle of wine ( for someone new to linux it can be terrifying) and you should get much better overall performance that way.

another option, if you want and emulator with commercial support is to try CrossOver Office, which will also allow you to run MS Office, but gives you the option of having commercial support from a company. Open Office and if you run KDE, KOffice are still the way to go, in my opinion, though. I know lots of people who are moving to using OpenOffice even under windows, not just under Linux.

It seems that MS Office has been successfully installed under Wine in Linux. Wine is an app that is used as an interface to run certain Windows apps when using Linux, but, you are not actually installing Office 2007 under Linux. What Boot Camp is to the Mac, Wine is to Linux.You could also install virtualbox in Linux, Install Windows in virtualbox then install Office 2007 and run it in a virtual environment.http://appdb.winehq.org/objectManager.php?sClass=version&iId=4992OR, do what the rest of us do and download a free application called OpenOffice which was designed for Linux, and does most of what MS Office 2007 does, without having the hassle of trying to run Windows applications under Linux.OpenOffice is also available for Windows, in case you would like to try it before making a decision. You can download OpenOffice for Windows here:http://download.openoffice.org/other.html
